Specific implementation mode
To keep the purpose of the present invention, content and advantage clearer, with reference to the accompanying drawings and examples, to the tool of the present invention
Body embodiment is described in further detail.
The present embodiment proposes that a kind of front guide supporting device of strap cam retaining mechanism, structure are as shown in Figure 1.This is leading
Include height adjustment mechanism and cam lock holding mechanism to support device.Wherein, height adjustment mechanism include front jocket wheel inner tube 1, it is preceding
Guide wheel outer tube 2, screw-nut 3, bevel gear 4 and crank 5.One end of front jocket wheel inner tube 1 is connect with front jocket wheel 6, other end insertion
Front jocket wheel outer tube 2, and connect with front jocket wheel outer tube 2 by screw-nut 3.The upper end of screw-nut 3 is installed by bevel gear 4, umbrella tooth
Wheel 4 is connect with the crank 5 on front jocket wheel outer tube, bevel gear 4 and screw-nut 3 is rotated by crank 5, before capable of adjusting
The length that guide wheel inner tube 1 is stretched out in front jocket wheel outer tube 2, to adjust the height of front guide supporting device.
Cam lock holding mechanism 7 is mounted on the middle part of front jocket wheel outer tube 2, passes through the locking and release of cam lock holding mechanism 7, energy
Enough lockings and release realized to the rotational action of height adjustment mechanism.Wherein, cam lock holding mechanism 7 include cam handle 8, in
Countershaft 9 and inside and outside rotary sleeve 10.Cam handle 8 is connected with jackshaft 9, and jackshaft 9 is connected with inside and outside rotary sleeve 10, inside and outside rotation
Set 10 is connected with front jocket wheel outer tube 2.By the rotation of cam handle 8, jackshaft 9 can be tensed or be unclamped, and then will be inside and outside
Rotary sleeve 10 is compressed locked or is unclamped, to realize locking and release to the rotational action of front jocket wheel outer tube 2.
As shown in Fig. 2, when cam handle 8 is in locked position, the most significant end of cam handle 8 is played a supporting role and is tensed
Jackshaft 9 so that inside and outside rotary sleeve 10 is compacted locked, can not rotate, and then locks front jocket wheel outer tube 2, to lock height
Regulating mechanism.As shown in figure 3, when cam handle 8 is in released position, jackshaft 9 unclamps so that inside and outside rotary sleeve 10 is also loose
It opens, it is possible thereby to rotate front jocket wheel outer tube 2, and then rotates height adjustment mechanism.
The front guide supporting device of the present embodiment when in use, as shown in figure 4, height adjustment mechanism perpendicular to ground and
It is cam locked the locking of mechanism 7, the height of front guide supporting device can be adjusted to suitable position by the rotation of crank 5.It pushes away
When motor-car, the front jocket wheel 6 of 1 lower part of front jocket wheel inner tube, front jocket wheel 6 is universal wheel, can change direction with surface conditions.It is packing up
When front guide supporting device, as shown in figure 5, the rotation by crank 5 takes in front jocket wheel inner tube 1 to front jocket wheel outer tube 2, unclamp
Front guide supporting device is rotated by 90 ° by cam lock holding mechanism 7 entirely around cam lock holding mechanism 7, then by cam lock holding mechanism 7
Locking, you can front guide supporting device is integrally packed up and locked.As a result, vehicle when driving, front jocket wheel 6 does not interfere with trailer
Approach angle and minimum ground clearance.
The above is only a preferred embodiment of the present invention, it is noted that for the ordinary skill people of the art
For member, without departing from the technical principles of the invention, several improvement and deformations can also be made, these improvement and deformations
Also it should be regarded as protection scope of the present invention.
